The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
And one of the more exciting ones that has been studied over the years is this notion of hormones from bone traveling in the blood stream to the brain and enhancing the function of the hippocampus. If the words hormones from bones is surprising to you, I'm here to tell you that yes, indeed, your bones make hormones. We call these endocrine effects.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

So they're effectively acting as hormones. And one such chemical is something called osteocalin. Now these findings arrive to us through various labs but one of the more important labs for sake of this discussion today is the laboratory of Eric Kandell at Colombia medical school. His laboratory has studied the effects of exercise on hippocample function and memory and other laboratories have done that as well. And what they found is that cardiovascular exercise and perhaps other forms of exercise too, but mainly cardiovascular exercise creates the release of osteocalin from the bones that travels to the brain and to sub regions of the hippocampus and encourages the electrical activity and the formation and maintenance of connections within the hippocampus and keeps the hippocampus functioning well in order to lay down new memories.
